This looks like a good brand. Agree, disagree? It also looks cheaper. Looks like it would only take $21 to get the highest recommended EPA and DHA for a whole month.
That's a lousy brand, to be honest. Look at the serving size--two capsules. That's 180 mg of EPA and 120 mg of DHA per capsule. Taking it at high doses will probably make you feel sick. You want to find a brand where the EPA + DHA > 500 mg per capsule, that one only has 300 mg per capsule.
Occasionally you can find good deals at Costco, places like that for ultra-refined fish oil. GNC also carries good brands. Shop around.
No, I take liquid fish oil myself, but again check the label carefully to make sure it is concentrated, otherwise at the dosages I recommend it might cause nausea.
